Thematics and Design: The game is set in a technologically advanced dwarven mine, with a giant drilling machine serving as the reel set. The design is detailed and imaginative, blending classic fantasy dwarf elements with cool steampunk machinery, creating a unique and engaging world.
Graphics and animations: The graphics are crisp and well-polished. The drilling animation as the reels expand is a fantastic visual touch. The various gems and tools are brightly colored and stand out against the metallic background of the mine.
Sound Accompaniment: An adventurous and slightly mysterious soundtrack plays, accompanied by the mechanical sounds of the drill, clanking metal, and the echoes of the mine. The audio perfectly complements the theme of underground exploration.
Regular Symbols: The low-paying symbols are the four card suits (clubs, diamonds, hearts, spades) carved from stone. The high-paying symbols are mining equipment: a shovel, a pickaxe, a lantern, and a helmet. The dwarf’s helmet is the most valuable premium symbol.
Special Symbols:
Starting your dig is easy. Set your bet amount, then press the ‘Spin’ button to power up the drill. The game starts on a 5×4 grid, but landing Bonus symbols will expand it. To see how this works, you should try the free slot machine version on our site. The game is fully optimized for a deep dive on any mobile slot screen.
The core base game feature is triggered by landing a Bonus symbol on reels 1, 3, or 5. This will cause the reel to expand downwards by one row for that spin, increasing the ways to win. It’s possible to expand all three reels, reaching a full 5×7 grid with 16,807 ways to win.
Landing three Scatter symbols anywhere on the reels will trigger 10 free spins. During this entire bonus round, the reels are fully expanded to the maximum 5×7 size, ensuring that all 16,807 ways to win are active on every single spin.
This is a special, higher-potential bonus round. Below the reels are four collection meters, one for each color of gem. When you land a Collectible Gem on the expanded rows, it is added to its corresponding meter. Once you collect 5 gems of the same color, you will trigger 5 Collection Free Spins. In this mode, the reels are also fully expanded, but the only high-paying symbols that will appear are the ones that correspond to the color of the gems you collected (e.g., green gems trigger spins with only helmets).
RTP: Dwarf Mine is a very high RTP slot, featuring a fantastic Return to Player of 96.8%. This is significantly above the industry average and makes it an extremely attractive game from a statistical perspective.
Volatility: The game has medium-high volatility. The base game offers frequent excitement with the expanding reels, but the biggest treasures are buried in the Free Spins rounds, especially the highly lucrative Collection Free Spins where only the top symbols are in play.
Dwarf Mine is a brilliantly inventive and engaging slot. The expanding reels mechanic keeps the base game fresh and exciting, while the dual free spins modes provide excellent short-term and long-term goals. The high RTP is a massive plus, and the theme is executed with Yggdrasil’s usual high level of quality. It’s a fantastic adventure that offers plenty of depth and replayability. Grab your pickaxe—this is one mine that’s well worth exploring.
